How much coolant goes into the radiator for an 1985 f150?

There's no single answer to how much coolant goes into a 1985 Ford F-150's radiator. The amount varies depending on the engine size and whether you're just filling the radiator itself or the entire cooling system.

To find the correct amount:

1. Check your owner's manual: This is the best source of information. It will specify the coolant capacity for your specific engine.

2. Look for a sticker: Sometimes, a sticker under the hood (often near the radiator cap or expansion tank) will indicate the coolant capacity.

3. Consult a repair manual: A Haynes or Chilton repair manual for your specific year and model F-150 will provide the correct coolant capacity.

4. Drain and measure: This is the most accurate method, but it requires draining the coolant. Once drained, refill and measure how much coolant it takes to fill the system to the proper level. Be sure to use the correct type of coolant (check your owner's manual).

Without knowing the engine size (e.g., 300 I6, 302 V8, 351 V8, etc.), it's impossible to give you a precise figure. Expect the capacity to be somewhere between 10 and 15 quarts (or liters) for the entire system, but that's just a rough estimate. Always refer to your owner's manual for the most accurate information.
